 ==One Sample T-Test Example==
-Go to the [http://www.socr.ucla.edu/htmls/ana/OneSampleTTest_Analysis.html SOCR One-Sample T-Test Applet]. We will demonstrate One Sample T-Test with some SOCR built-in examples.  This example is based on the data taken from the statistical program "R." For more information of the R program, please see [http://cran.r-project.org/ CRAN Home Page]. The dataset used here is "shoes" under R's "MASS" library. In the dataset, ten boys are given to the wear of shoes of materials A and B for one foot. The worn level is recorded and difference is obtained. We'd like to find if one material is better than the other. The difference is calcualted by B - A. (Note: this example is also used in another three SOCR demonstration: [http://wiki.stat.ucla.edu/socr/index.php/SOCR_EduMaterials_AnalysisActivities_TwoPairedT Two Paired Sample T-Test], [http://wiki.stat.ucla.edu/socr/index.php/SOCR_EduMaterials_AnalysisActivities_TwoPairedSign Two Paired Sample Sign Test], and [http://wiki.stat.ucla.edu/socr/index.php/SOCR_EduMaterials_AnalysisActivities_TwoPairedRank Two Paired Sample Signed Rank Test]. If you'd like to see the data of each material, go to the page of these activities or directly look for them in the SOCR Applet.
